SHINGLING-BRACKET.

Specification of Letters Patent.

Application filed January 22, 1909.

Patented Apr. 5, 1910. Serial No. 473,682.

To all lwhom it may concern:

Be it known that I, FRANCIS L. SPRING, a citizen of the United States,residing at Townsend, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Shingling-Brackets, of which the following is a specification.

This invention relates to an improved shingling bracket, and the objectis to provide a light, strong bracket which may be adjusted to fit roofsof different pitches and which may be readily folded so as to occupy butlittle sp'ace; and the object is further to provide a bracket of thisclass, the base of which may be secured to the shingles by nails, andafter a course of shingles has been laid on top of the base of thebracket the same may be readily disconnected from the nails withoutlifting the shingle which lies upon the base.

A still further object is to provide a strong and convenient device forsecuring to the bracket the adjustable stop against which rests theplank upon which the workmen sit. o

In the attainment of the objects above enumerated, I have produced abracket which is simple in construction and economical to manufacture.

The invention consists in the novel features of construction and in thecombination and arrangement of parts set forth in the followingspecification and particularly pointed out in the appended claims.

Referring to the drawing: Figure 1 is a plan of a shingling bracketembodying my invention, the same being shown in place on the shingles ofa roof. Fig. 2 is a sectional view taken on line 2 2 of Fig. 1. Fig. 3is a side elevation of the bracket when folded. Like numerals refer tolike parts throughout the several views of the drawing. In the drawing,is a base comprising two plates 6 and 7. To the plate 6 is secured ayoke 8, to which yoke a pair of arms 9, 9 are pivoted at 10, said armsterminating at their lower ends in spurs 11 adapted to stick intothe/roof of the building. To the plate 7 is secured a bracket 12 towhich bracket a pair of arms 13, 13 are pivoted at 14, said arms beingpivoted at 15 to the rarms 9. The arms 13 are adapted to support theusual plank 16, said plank being held in position on said `arms by meansof a stop 17 adjustably secured to said arms by means of a clamp screwor bolt 18' extending between said arms and through a clamp plate 19located on the under side thereof, a thumb nut 2O having screwthreadedengagement with said screw being provided to coperate with said screwand clamp plate to secure'the stop 17 to the arms 13,.it bein understoodthat said stop may be adjuster longitudinally of said arms fordifferentwidths of planks. f

InY order that the arms 13 and planks 16 may be approximately horizontalregardless of the pitch of the roof the angle of the arms 9 and 13 toeach other and to the base 5 may be varied by moving the plates 6 and 7longitudinally of each other, said plates for lthat purpose beingadjustably connected together preferably in the following manner. Theplate 6 is provided with a series of holes 21, while the plate 7 isprovided with a projection 22 formed thereon or secured thereto, whichprojection is adapted to enter any one of said series of holes.Embracing the plates 6 and 7 is a slide 23 which normally holds saidplates against lateral displacement relatively to each other, said slidebeing adapted to -be moved from the position shown inA Fig. 2 toward theright out of engagement with the plate 6 and when said slide is thusdisengaged the plate 6 may be lifted until the projection 22 passes outof the hole 21 in which it is located and said projection may then beplaced in another hole of the series,V thus changing the length of thebase 5 and consequently changing the angular relation of the arms 9 and13 to each otherandcto said base, it being understood that thev slide 23is again moved toward the left so as to embrace both of the plates. Theplate 7 is provided adjacent to the free end thereof with two preferablyV-shaped notches 24 and 25 extending thereinto from opposite edges,respectively, thereof, saidnotches being ,1o-- cated out of alinement-with each other longitudinally of said plate, said' plate beingpreferably narrowed vsomewhat at its right hand extremity.

In the use of the bracket, the workman, standing upon a scaffold at theside of the house, lays upon the roof several courses of shingles, thenumber shown in the drawing being tive. lle then places two or more ofthe brackets upon the courses of shingles thus laid, in the positionshown and drives into the upper course of shingles two nails 26 and 27in the notches 24s and 25, respectively, as shown in Fig. 1. Thesenails, when thus driven, prevent the bracket from sliding downwardly onthe slope of the roof, the spurs 11 also tending to preventsuch slidingmovement as well as preventing lateral movement of the bracket.

It will be noted that the arms 9, 9 diverge toward the lower endsthereof in such a manner as to give the bracket considerable rigiditylaterally. The plank 16 is then laid upon the brackets in the usualmanner and the workman sitting thereon then lays several more courses ofshingle-s up on the slope of the roof as far as he can reach. Afterthese new courses of shingles have been laid, other brackets are thenput in place thereon in the manner hereinbefore described andsubsequently the series of brackets previously used lower down on theroof are removed in the following manner. Each bracket is liftedslightly to disengage the spurs 11 from the shingles and said bracket isthen swung laterally from the position shown in full lines in Fig. l tothe position indicated in dotted lines therein so that the plate 7 maythen be withdrawn from between the nails 26 and 27 and subsequently theworkman strikes the shingle above said nails to drive them fully intothe roof so that said shingle will lie in close Contact with the shingletherebeneatl'i.

Vhen it is so desired, the bracket may be conveniently folded so as tooccupy but a small amount of space, this being accomplished by firstloosening the stop 17 and moving the same from the position shown inFig. 2 to a position adjacent to the pivot 14. The slide Q3 is thenmoved toward the right out of engagement with the plate 6 and said plateis then lifted until the projection 22 passes out of the hole 21 inwhich the same is located. The arms 13 are then swung in the directionof the arrow a, Fig. 2, through an angle of somewhat less than 900 andthe plate 6 is then swung in the direction of the arrow Z) unt-il thesame rest-s against the upper side of t-he arms 9. The arms 9 are thenswung in the direction of the arrow c until they very nearly coincidewith the plane of the arms 13. The arms 13 are then swung in thedirection of the arrow CZ until the parts occupy the position shown inFig. 3, the bracket when thus folded being very compact and occupyingbut a small amount of space.

Having thus described my invention,what I claim and desire by LettersPatent to secure is:
